Researching 1939 Motion Picture Production

I am researching motion picture production in 1939. Can anyone help me with what cameras, blimps, heads, dollies, lights- basically any piece of motion picture equipment that might have been on the set of Mr. Smith Goes to Washington? Also, any place some of this equipment is on display?
